To all whom it may] concern: i

Be it known that I, BENJAMIN H. Jones,

a citizen of the United States, residing at St. Louis, and State of Missouri, have .invented certain new and useful Improvements in Spring-Mattresses and Supports Therefor, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof. I

My invention has relation to improvements in spring mattresses for beds and supports therefor, and consists in the novel features of construction more fullyset forthin the specification and pointed out in the claims. The object of the present invention is 'to provide a spring mattress having a frame, the component parts of which shall be spot welded together, thus resulting in a strong, durable construction possessing the rigidity of a single piece. The advantage of thus constructing the frame lies principally in its rigidity, and fu rther in that itinay be handled as a single unitwhile building up the mattress. A further object is the pro: vision of a marginal, supporting member having brackets to which the marginal springs are secured,and also having an adjustable supporting arm or slidewhereby the mattress may be supported on the side-rails of the bed. A further object is the provision of a supporting slide for the mattress that is adapted to cooperate with either a regular or inverted side-rail or a wooden bed siderail, the slide being provided with prongs that will bite into and grip the wooden siderail. Further and other advantages will be better apparent from a detailed description of the invention in connection with the accompanying drawings in which- Figure 1 is a plan view of a part of my improved mattress and supporting slide therefor; Fig. 2 is a side elevation of one end of the mattress with the slide in place; Fig. 3 is a vertical transverse section on the line 3--3 of Fig. 1 with parts omitted; Fig. 4 is an enlarged vertical cross sectional detail on the line 4-4: of Fig. 1 showing the frame members spot-welded; Fig. 5 is a perspective view showing how the springs are seated over the bosses formed on the frame; Fig. 6 is a perspective View of the supporting slide cooperating with a regular rail; Fig. 7 is an enlarged cross sectional detail 55 through the slide taken on the line 7 -7 of 1g. is a perspective view of the sl de cooperating with an inverted side-rail; Fig. 9 1s a perspective view of the slide cooperating with a wooden side-rail; and Fi 10 1s an outllne of themattress showing tlie marglnal supports and supporting slides mounted thereon.

Referring to the drawings F represents the mam frame of the mattress composed of a series of longitudinal metallic bands 1 and a ser es of transverse metallic bands 2, the bands 1 having bosses 3 bent from them between their points of intersection with the bands 2, and bosses 3 bent from the bands 1 and 2 attheir points of intersection. The bands 1 and 2 are spot-welded together as shown at 20 (Fig. 4) the weld in this instance being at the boss formation 3, but, of course, for a ditferent spacing of the bosses this may not be the case, the object be ng to weldthe bands 1 and 2 at their points of intersection irrespective of the location of the bosses. Heretofore in mattresses of this type the bands composing the frame have been riveted together, thus permlttlng of a distortion ofthe frame when certam stresses are imposed, the rivet actlng a-sa pivotal point for the movement; but I have overcome this disadvantage by spotwelding the points of intersection of these bands, the resulting frame being virtually integrally formed.

y The frame further comprises a marginal supporting member 4: on each side of the mattress, the supporting member in the present instance being an angle iron, to the I top leg of which a series of smaller angles 5 are secured in spaced apart relation, the angles 5 constituting holding members for the marginal springs 6, the lower ends of said springs being passed through openings 0 in the angles 5. A sub-frame F comprising outer members 7 and transverse members 8 is suspended from the marginal member 4: by struts a, the frame F being provided only when a double deck mattress is desired, in which case the lower ends of the intermediate springs 6' (which are double deck springs) are passed through the openings 0' in the members 8. the springs being seated on the bosses 3, 3 intermediate their extremities, the members 1 and 2 entering be tween adjacent coils of the springs as shown in Fig; 5. The upper coils of the springs 6, 6 are woven together by means of wires 9 and a marginal wire 10 extends around the entire mattress, the end springs 6 being securedto the wire 10 by clips 11, and the marginal springs 6 are bound to the Wire 10 by connecting wires 12. .The method of weaving or otherwise arranging wires 9 and 10 together with the springs to form the supporting surface of the mattress is old and is not claimed herein. However, a mattress or this type embodying a main frame, the

component parts of which are welded t0- gether to form 'anint'egralunit, is new so far as I am aware.

In order to support the mattress on the sideqrails of the bed I have provided a pair of adjustable arms or slides 13 slidably mounted on the supportingmembers 4. beneath straps 14 riveted to the members 4. The slide has a depending lug 15 bent from its inner edge, and a pair of fingers or prongs l6" bent downwardly from its outer edgeythe lug 15 and fingersllG operating to confine the slide'on the member 4. When the mattress is positioned in a bed provided with a regular side-rail 17 (Fig.

6) the slide is extended so that the fingers 16 will project over theouter edge of the 17, the lug'l5 operating to prevent'withdrawa'l or the slide from the strap 14:; If the bedis provided with an inverted siderail'17" the'fingers 16 will rest 011 the horizontal leg of the side-rail as shown in Fig. 8. lVhen-it is desired to place my improved mattress"embodying the slide B on a bed provided with a wooden side-rail 17 the fingers-or prongs 16 ofthe slide will engage the rail'17 ass'hown in Fig. 9, and when weight is im oseaon the mattress the prongs 16 wil'l'bite into the wood rail and effectivelyprevent displacement. The slide 13 has its lateral edges 0, e bent downwardly,

resulting in a channel formation which greatly increases'the strength of the slide, and'permits of'using lighter material in making the same, and the lug 15 and prongs 16 will, of course, project downwardly bclow the plane of the edges 0.

It will be readily understood from the foregoing that I have provided a mattress that possesses lightness and durability together with great rigidity, embodying means whereby it may be supported on practically any manner of side-rail forming a part of a bed. l urthcrmore the slide itselil may be susceptible to other uses not in connection with a bed, all of which I wish to avail myself of together with the modifications to which the invention is susceptible.

Having described my invention, I claim:

1. In a device of the character described, a member provided with a strap. a channelshaped slide mounted between the member and strap, and means for holding said slide in place.

2. In a device of the character described, a supporting member having a strap scoured. thereto, an adjustable arm mountcd between the supporting member and the strap, said arm being channel-shaped and having a downwardly projecting lug on its inner end, a pair of prongs bent downwardly from the outer end of the arm, said prongs and lug operating to maintain the arm on the supporting member.

3. In combination with the side rails of a bed, a spring mattress having marginal supporting members, slides mounted thereon, each of said slides having :1 lug "bent downwardly from its inner edge and a pair of prongs bent downwardly from its outer edge, the lug andprongs operating to maintain the slide in engagement with the supporting member, and the prongs operating to engage the bed side-rail to hold the mat tress in place.

In testimony whereof I allix my signature.

BENJAMIN H. JONES.
